linux查看cpu核心数的命令，方便人类查看

1、一键执行

lscpu | grep -E "^(CPU\(s\)|Core|Socket|Thread|Model name)" | sort

2、脚本执行，脚本内容

echo "==================== CPU 核心信息 ===================="
echo "总逻辑CPU核心数: $(lscpu | grep '^CPU(s):' | awk '{print $2}')"
echo "物理CPU个数: $(lscpu | grep 'Socket(s):' | awk '{print $2}')"
echo "每个物理CPU的物理核心数: $(lscpu | grep 'Core(s) per socket:' | awk '{print $4}')"
echo "每个物理核心的线程数: $(lscpu | grep 'Thread(s) per core:' | awk '{print $4}')"
echo ""
echo "📝 计算验证:"
echo "总物理核心数 = 物理CPU个数 × 每个CPU物理核心数"
echo " = $(lscpu | grep 'Socket(s):' | awk '{print $2}') × $(lscpu | grep 'Core(s) per socket:' | awk '{print $4}')"
echo " = $(($(lscpu | grep 'Socket(s):' | awk '{print $2}') * $(lscpu | grep 'Core(s) per socket:' | awk '{print $4}'))) 个物理核心"
echo ""
